I have the following question: I installed fvdw-sl firmware on my Cloudbox, using a fresh hard drive instead of the original 3 TB one. I want to use this 3TB drive for something else, but before that I want to back up the original Lacie firmware, so that I can restore the Lacie NAS one day (not that I think I will ever be willing to use it but it won't hurt to have this possibility).
When I ran the lacie-firmware-backup script, it tries to format sda9 and then it fails.
I found this thread on plugout.net http://plugout.net/viewtopic.php?f=28&t=1547&start=10, and backed up the partitions sda1 sda2 and sda3.
My question is, is this enough for restoring the Lacie NAS. I don't need the data which was on the NAS before taking the drive out, I just want to be able to restore the Lacie firmware.

Sorry if this was already discussed somewhere in the forum, I just could not find it.

You will need to make copies of partitions 1-5 by using for example command dd if you use linux do do the job. But note that the image will be big for partition 4 and 5 (1.5 GB each), so it will take some tinme. The partition images you could compress later using a program like 7zip or so.
You could also try to copy only the file systems in the partitions 4 and 5 but for that you will will need to assemble the raid array first to be able to mount the partition.

Yes to be save you could also copy partition 6.
Partition 7 is swap when you run out of ram. Partition 8 contains the shared folders (your files) that you stored on th nas.
Of course you also need the info on partition table to be able to recreate it.
